PLUG-TOBACCO MACHINE.

SPECIFICATION forming part of Letters Patent No. 252,899, dated January 31, 1882,

Application filed March 98,1881. (No model.)

To all whom it may concern Be it known that I, JOHN RAMMING, a citizen ot' the United State's,residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Plug-Tobacco Machines, of which the following is a specification.

This invention relates to certain improvements in that class of plug-tobacco machines in which the loose tobacco is fed or carried by endless carrier-belts between a set of rolls and pressed intoshape, the pressed strip thus formed passing through a set of longitudinal slitting-cutters, and then through asetof transverse cutters, which divide the strip of tobacco' into the required size to form the usual plug of tobacco; and the objects of my improvements are, first, to provide an improved construction of parts, whereby a more even and uniform pressure is imparted to the plug-strip, and the tobacco more evenly fed or carried between the pressing-rolls, thus insuring uniform thickness and weight of the resulting plugstrip; second, to provide an improved means for driving the upper pressing-roll, and allow for any required vertical adjustment of the same without altccting itsdriving connections; third, to provide an improved means for transversely dividing the pressed strip of tobacco into plugs while said strip is moving out of the machine. I attain these objects by the mechanism illustrated in the accompanying drawing, which is a vertical section of the machine.

Areprcscnts the main frame, in which arejournaled the rolts B 0, between which the loose tobacco is carried by endlrss carriers or belts D D, surrounding said rolls, to be pressed into a compact shape, a pair of endless belts, E, be ing used to carry the loose .tobacco from the spreading table or box to the carriers DD. The pressed strip of tobacco, as itpasscs from the rolls B G, is acted on by circular slitting knives or cutters F, that split it into the required width of a plug of tobacco.,

The construction so far described is usual to plugtobacco machines, and no novelty is claimed therefor in the present case.

The novel features of my improvement are, first, in the arrangcmentand construction of the cutter for dividing the strip of tobacco aforesaid into the required lengths of tobaccowhich is against a cylinder or roll, G, of rub- Each cutter g her or other elastic material. is provided with a spring-follower, 9 which acts, after the cutter has severed the tobaccoplug, to push the end of the plug up out of the line of travel of said cutter, and prevent iiijury to the same by the cutter in its forward movement. Y

The second novel feature of my invention consists in an improved manner of driving the upper roll, B, by means of a small pulley, B, and the carrier-belt D, a belt-tightener drum, D being provided to take up any slack that may occur in the belt. lows of a free vertical movement of the roll B to or from the under roll, (3, (which is arranged -.in-non-ad justable boxes.) without in any way interfering with its driving mechanism orconnections.

The third novel feature of my invention conclined throat toward the pressing rolls, the ac tion of which throat is twofold, first, to partially press the tobacco, and, second. to evenly and uniformly spread the loose tobacco before it can pass in between the pressing-rolls.

The object of pivoting the plate H is to ad- This construction almit of its free end following up any adjust I ment ofthe adjustable upper pressing-roll, B, the frictioirroller It being provided to ieduce friction at the point of contact between the free end of the plate H and the roll B.

In a plug-tobacco machine, the upper pressing-roll, B, made vertically adjustable, in combination with the non-adjustable drivingpulley B, tightener-pulley D and carrying and driving bclt D, all arranged substantially as described, and for the purpose set forth. 1 2.
